Giant cell tumors of the synovial tendon sheaths (GCTSTS) are a localized form of hemopigmented villonodular synovitis. They mainly affect the hands. This study aims to analyse the epidemiology, clinical and therapeutic characteristics of GCTSTS, to assess the results of surgical treatment and to identify risk factors for recurrences. We conducted a retrospective data collection from medical records of 50 patients with GCTSTS of the hand between 1992 and 2016 in the Department of Orthopaedics at the Hospital of Sahloul (Sousse-Tunisia). The clinical and epidemiological features of GCTSTS have been specified. The average age of patients was 33 years (9-69 years), the sex ratio was 0,6. Constant swelling (100%), joints inter-phalangeal mobilization trouble (6%) and digital pain (18%) were the most frequent reason for consultation. All tumors were located at the level of the digital region, especially at the level of the index (42%). It occurred on the palm of the hand in 66% of cases. All patients underwent surgery; macroscopically GCTTS appeared as an encapsulated polylobed and yellowish brown tumor, extending into the flexor tendons sheath(4 cases) and under the extensor tendon (2 cases). We noted a single case of recurrent cancer (2%) which was treated surgically. The functional results were good in all cases. The diagnosis of GCTTS should be evoked when there is evidence of digital swelling. Their management is based on surgery which is difficult and should be performed correctly to avoid recurrences.

Treatment of unstable fractures of metacarpals and phalanges remains subject of controversy. Few series have been reported in the literature, making their analysis difficult. We provide a retrospective study involving 12 patients, operated on by this technique for displaced fractures of the metacarpals and phalanges, over a two year period. The final overall results were good in 75% of the cases, average in 16,5% of the cases and bad in 8,5% of the cases. Stability of mini plates in unstable fractures of the metacarpals and phalanges allowed early mobilization of hand joints, thus avoiding stiffness. [ABSTRACT FROM AUTHOR]

MASSON described glomus tumour as a benign neuromyoarterial proliferation. It represents approximately 1%-5% of all tumors of the hand. Pain is the main clinical sign. Definitive diagnosis is based on a body of evidence: clinical and radiological but only histology will allow confirmation. We conducted a retrospective study of 11 patient whose average age was of 36, 27 years (range 8-48 years), with a mean follow-up period of 34,40 months. All patients underwent surgical excision. This strategy allowed us to achieve satisfactory results. [ABSTRACT FROM AUTHOR]

La ténosynovite tuberculeuse est une localisation rare de la tuberculose. Le diagnostic en est souvent tardif en raison de manifestations cliniques souvent pauvres et chroniques. Nous rapportons une observation de ténosynovite tuberculeuse du 2ème rayon de la main droite d'évolution favorable sous traitement antituberculeux. [ABSTRACT FROM AUTHOR]

Les auteurs rapportent une série de 90 patients, présentant une section tendineuse des fléchisseurs de la main, et suivis avec un recul moyen de 8 mois (min: 2 mois; max: 13 mois). La lésion était localisée dans 12% des cas en zone I, 46% des cas en zone II, 2% en zone III et 25% des cas en zone IV et V. Pour le pouce (13 patients), 10 cas en zone T2 et 3 cas en zone T3. La technique opératoire utilisée était les sutures tendineuses en cadre de Kessler modifié, associée à un surjet épitendineux. Nous avons obtenus 54% de très bons résultats, 34% de résultats moyens et 12% de mauvais résultats. Pour le pouce les résultats semble moins bons avec un taux de résultats médiocre de 48%. Certes les chiffres de cette série sont moins bons que ceux des autres séries publiées dans la littérature. Les facteurs influençant les résultats sont d'abord l'utilisation d'immobilisation postopératoire systématique ainsi que le mécanisme d'agression, et la localisation à la zone II et au pouce. Les complications mécaniques sont représentées par 7% de rupture, toutes au niveau de pouce, et 31% des adhérences tendineuses (soit 30 cas), dont 19 en zone II, l'infections (22%) et 4% des cas d'algodystrophies.
